Your copy bot runs, but the equity and P&L drift wallet-to-wallet because the numbers are rebuilt from live API snapshots instead of from the trade ledger itself. I'd fix that by making the reconciliation event-sourced: pull the full fill history from the Polymarket/Polygon side, sort deterministically, and replay every buy, sell, partial fill and position scale to derive cost basis (weighted average), realized and unrealized P&L, and open positions from first principles. That's what makes it wallet-agnostic instead of needing per-wallet patches. For the messy parts, I'd add settlement handling that closes positions at market resolution, idempotent event IDs so delayed or duplicated blockchain events don't double-count, and validation checks that flag when API equity diverges from the replayed ledger, with logging so discrepancies are traceable to a specific fill. On background: I've built trading and blockchain reconciliation systems reconciling on-chain events against internal ledgers, plus Polygon/EVM transaction parsing and financial P&L engines in Python. I'll test against several wallets with different styles so results stay consistent, and hand over clean, documented code. Does the bot already store its own trade history somewhere, or should P&L be rebuilt purely from on-chain and API data? Muhammad Saad

@seospider

Hello, Your bot needs a wallet-agnostic ledger that rebuilds every fill, position, settlement, and balance instead of depending on unreliable API snapshots. The $10–$30 budget is acceptable since the foundation is already complete. I’ve worked on Python crypto-trading systems covering live positions, trade history, fees, equity tracking, and P&L validation. My approach is to replay wallet events chronologically, calculate weighted cost basis, separate realized/unrealized P&L, detect missing events, and verify results across multiple wallets. Which Polymarket API/indexer and position schema does the current bot use? Best Regards Hasan

@FizzaNadeemK

Hi, I’ve worked on Python projects involving API data processing and transaction reconciliation, so I understand how small inconsistencies can lead to incorrect P&L and equity calculations. Your goal requires fixing the reconciliation logic at its source rather than adding wallet-specific workarounds. The main challenge is handling edge cases like partial fills, delayed events, and position scaling while maintaining accurate cost basis and realized/unrealized P&L. I’d review the existing logic, implement a wallet-agnostic reconciliation engine with validation and error logging, then test it across multiple wallets to ensure consistent results. I’ll deliver clean, documented Python code, improved reconciliation logic, comprehensive testing, and recommendations for long-term reliability. Best Regards, Fizza

@AndrewJSMAN

I’ve implemented P&L and equity reconciliation engines for EVM-based trading systems handling partial fills, API inconsistencies, and delayed events before, so this fits squarely in my domain. I’ll refactor the current equity logic by isolating raw trade events from Polymarket’s API and Polygon events, then build a wallet-agnostic reconciliation pipeline that tracks cost basis per position with FIFO/LIFO selection, handles market resolution via price feeds, and flags settlement gaps or reorgs. The system will log discrepancies in real-time with timestamps and event hashes for replayability, validate against on-chain state via Alchemy or Infura, and include unit tests for partial fills and multi-scalar position scaling. You’ll get a clean Python package with modular ingestion, reconciliation, and reporting layers ready for deployment. I can start immediately. Thanks, Andrii.

@cliftonc20

Hello, building a Polymarket trading bot is mostly an execution-systems problem, and I’ve designed production Python services where data flow, decision logic, and operational safety matter more than the surface script. The real engineering risk is not placing an order; it’s keeping market data, signal evaluation, and execution state consistent under latency, retries, and partial fills. The closest relevant work here is Dent-Cloud, where I designed continuous data pipelines and prediction services around live operational inputs, and Enterprise ProxyTool Client App, where I separated control-plane logic from real-time execution paths for reliability. I usually structure systems like this as distinct layers: market ingestion, strategy evaluation, execution, and observability. That separation makes it easier to test strategy logic independently from order placement and to add guardrails around exposure, duplicate actions, and recovery after disconnects. For long-term use, I’d also define event logging, state snapshots, and failure handling up front so the bot is explainable after trades, not just functional during a happy path. If useful, I can sketch the bot architecture first: data flow, decision loop, execution safeguards, and monitoring points. Clifton

@melopgabriel

Hi, your bot already works, but the real issue is reliable wallet-agnostic P&L and equity tracking across messy on-chain activity. That means handling partial fills, position scaling, settlements, and inconsistent API or indexer data without wallet-specific patches. I’ve built Python systems for trade reconciliation, event processing, and financial calculations where accurate cost basis and realized/unrealized P&L mattered more than just execution. My approach would be to trace each trade into a normalized ledger, then reconcile positions against wallet state and settlement events with clear validation and logging. I’d isolate the root cause of the equity mismatch, tighten edge-case handling, and keep the code clean and documented so it is easy to maintain. If you want this fixed properly, I can help review the current logic and harden it across multiple Polymarket wallets. Best regards, Gabriel

@jordanrafael7

Hello! I'll extend your Polymarket trading bot foundation with clean Python logic that handles real-time data feeds, executes trades based on your strategy rules, and keeps the system stable under live market conditions. I've built Python automation systems that integrate third-party APIs, manage asynchronous workflows, and handle structured data processing at scale. My work in Software Architecture ensures the bot's modules stay modular and maintainable, while my JavaScript and Python experience lets me work across your existing stack without friction or rewrites. Here's how I'll get you there: - Review your current foundation and identify the specific endpoints, triggers, and execution logic needed for Polymarket integration - Build or extend Python modules for order placement, position tracking, and error handling with clean separation of concerns - Test the bot in a controlled environment to confirm reliability before any live deployment What specific trading logic or triggers does the bot need to execute, and are there rate limits or API constraints I should account for in the design? I'm ready to start immediately and can work within your budget. Let's discuss the details and timeline through Freelancer messages. Best regards, Jordan Rafael G.

@arturg6

Hello, "Wallet‑Agnostic P&L Engine" - need accurate equity tracking across any Polymarket wallet. I will refactor the equity logic using a transaction ledger built with pandas, because pandas handles partial fills, cost basis and scaling efficiently. I automated a similar Python API workflow for video backup: https://www.freelancer.com/projects/automation/Automate-Reolink-Video-Backup-Script/reviews. I will also add retry buffers and event validation to cover missing or delayed blockchain events, ensuring the engine stays reliable even when the Polymarket API lags. Which Polymarket API endpoint are you currently using for trade data? Looking forward to working with you. Artur Giżycki

Hello, I’m an experienced Python developer with hands-on experience building trading automation, blockchain data processing, and reconciliation pipelines. I can review your existing Polymarket copy trading bot and implement a wallet-agnostic P&L and equity reconciliation engine that works consistently across different wallets. My approach is to reconstruct positions from on-chain events and trade history instead of relying solely on API responses. I will calculate realized/unrealized P&L, cost basis, position sizing, wallet equity, and open positions while correctly handling partial fills, scaling in/out, multiple buys and sells, market settlement, delayed events, duplicate or missing transactions, and other edge cases. I’ll also add validation checks, detailed logging, and consistency tests to quickly identify discrepancies. I have experience working with Python, EVM/Polygon transaction data, REST APIs, financial calculations, and trading-related automation. My focus is writing clean, maintainable code that produces accurate and reproducible results. I understand your budget ($10–30) and am happy to work within it. I can start immediately, review the current implementation, identify the root cause of the equity mismatch, and deliver a reliable reconciliation system tested against multiple Polymarket wallets. I look forward to discussing your bot and getting started.

@aribaumer

Hi, I will refine your Python Polymarket copy trading bot by building a universal P&L and equity reconciliation system to track realized and unrealized metrics, cost basis, and position sizing across any wallet. Let me know if you are fetching fill events via the Polymarket CLOB API or directly through Polygon RPC logs. Recently, I worked on a similar project developing an EVM blockchain position indexer and real-time P&L tracking engine for automated trading bots. The objective was to maintain accurate financial accounting across multi-wallet trades. I used Python, Web3, and API integration to calculate cost basis and settlement resolution. I look forward to discussing the project further and helping bring your vision to life. Best regards, Ariba
